SECTION 1—GENERAL GUIDELINES
SECTION 1—GENERAL GUIDELINES
WARNING
SECTION 1 - GENERAL GUIDELINES contains important information for the safe
operation and use of this product.
Operating the Lift
Check all parts for shipping damage before using. In case of damage, DO NOT use the equipment. Contact the dealer or customer service for further instructions.
DO NOT attempt any transfer without approval of the resident’s physician, nurse or medical assistant. Thoroughly read the instructions in this owner’s manual, observe a trained team of experts perform the lifting procedures and then perform the entire lift procedure several times with proper supervision and a capable individual acting as a resident.
Use common sense in all lifts. Special care MUST be taken with people with disabilities who cannot fully cooperate while being transferred. Although Invacare recommends that two assistants be used for all lifting and transferring procedures, our equipment will permit proper operation by one assistant. The use of one assistant is based on the evaluation of the health care professional for each individual case.
Make sure there is an audible click when mounting battery on the battery charger to confirm proper mounting. Otherwise, injury or damage may occur.
DO NOT exceed maximum weight limitation of the lift. The weight limitation for the 1900 and 1900S bath lift is 350 lbs.
ALWAYS keep hands and fingers clear of moving parts to avoid injury.
Lifting/Transferring
Invacare recommends the use of the safety strap and shoulder harness when using the bath lift. ALWAYS adjust the safety strap and shoulder harness for safety and comfort before transport.
During transfer, raise the seat so the resident’s feet are suspended from the floor. DO NOT roll caster base over objects such as carpet, raised carpet bindings, door frames, or any uneven surfaces or obstacles that would create an imbalance of the lift and could cause the lift to tip over. Wheelchair wheel locks MUST be in a locked position before transferring the resident into the wheelchair for transport.

1900/1900S Bath Lift
SECTION 1—GENERAL GUIDELINES
Performing Maintenance
Refer to Maintenance and Troubleshooting on page 17 for a maintenance schedule and procedures.
Regular maintenance of lifts and accessories is necessary to assure proper operation.
Casters and axle bolts require inspections every six months to check for tightness, wear, debris (such as hair and dirt) and that they roll free.
After the first twelve months of operation, inspect all glides, rollers, and fasteners for wear. If the metal is worn, the parts MUST be replaced. Make this inspection every six months thereafter.
The electric motor is sealed at the factory and if service is required, the motor unit MUST be returned to the factory for repair. DO NOT attempt to open the motor or obtain local service as this will VOID the warranty and may result in damage and a costly repair. Consult your dealer or Invacare for further information.
Electrical - Grounding Instructions
DO NOT, under any circumstances, cut or remove the round grounding prong from any plug. Some devices are equipped with three‐prong (grounding) plugs for protection against possible shock hazards. Where a two‐prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to contact a qualified electrician and have the two‐prong receptacle replaced with a properly grounded three‐
prong wall receptacle in accordance with the National Electrical Code. If you must use an extension cord, use only a three‐wire extension cord having the same or higher electrical rating as the device being connected. In addition, Invacare has placed RED/ORANGE WARNING TAGS on some equipment. DO NOT remove these tags. Carefully read battery/battery charger information prior to installing, servicing or operating your lift.

BATH LIFT
WARNING
DO NOT attempt any transfer of a resident without approval of the resident's
physician, nurse, or medical assistant. Thoroughly read the instructions in this
owner's manual, observe a trained team of experts performing the lifting
procedures and then perform the entire lift procedure several times with proper
supervision and a capable individual acting as a resident.
Adjustments for safety and comfort should be made before moving the resident.
Lock the rear casters of the bath lift when transferring an individual onto the seat.
Locking the rear casters will stabilize the lift and help prevent it from shifting during
transfer.
Each facility and each resident will require a unique set of instructions and
procedures to follow for each bath. Check with your supervisor and the resident’s
chart for the proper procedures to follow.
Review and practice the operation with able an bodied assistant before attempting
with a resident.
NOTE: Invacare recommends that two assistants be used for all lifting preparation and transferring to/from procedures; however, the bath lift can be operated with one assistant. The use of one assistant is based on the evaluation of the health care professional for each individual case.
Transferring into/out of the Bathing Unit
NOTE: For this procedure, refer to FIGURE 2.1 and FIGURE 2.2 on page 10.
NOTE: To transfer out of the bathing unit, reverse this procedure.

Care and Maintenance of Bath Lift
NOTE: Follow the maintenance procedures described in this manual to keep the 1900 and 1900S lift in continuous service.
The 1900 series lifts are designed to provide a maximum of safe, efficient and satisfactory service with minimum care and maintenance.
All parts of the 1900 series lifts are made of the best grades of steel, but metal‐to‐metal contact will wear after considerable use.
There is no adjustment or maintenance of either the casters or wheel locks, other than cleaning, lubrication and checking axle and swivel bolts for tightness. Remove all debris, etc. from the wheel and swivel bearings. If any parts are worn, replace these parts IMMEDIATELY. Invacare recommends a tightened arm rotation. The arm, when placed in the up position, should stay in the up position. Refer to Adjusting Arm Angle and Tension on page 19.
If you question the safety of any part of the lift, contact your Dealer IMMEDIATELY and advise him/her of your problem.
Detecting Wear and Damage
It is important to inspect all stressed parts. Replace any damaged or worn parts IMMEDIATELY and ensure that the lift is not used until repairs are made.
Cleaning the Lift
WARNING
The arms and seat of the lift MUST be cleaned and disinfected after each use with a
bath. Refer to Disinfecting the Lift on page 12.
1. A soft cloth, dampened with water and a small amount of mild detergent, wipe down all parts of the lift that are submerged in water from the bath. NOTE: The lift can be cleaned with non‐abrasive cleaners or disinfectants.
2. Remove and wash the safety strap. Refer to Removing/Installing the Safety Strap on page 15.
NOTE: Follow the instructions for washing the safety strap that are printed on the strap.

Inspecting/Tightening the Seat
NOTE: For this procedure, refer to FIGURE 3.2.
NOTE: Make sure the nuts and bolts holding the seat to the seat mounting bracket and the bracket to the lift column are tight at all times. Locknuts
1. Remove the shroud directly behind the seat by pulling it straight up. Bracket
2. Use a socket wrench to tighten the nuts attaching the bracket to the lift column. Locknuts
3. With a end wrench tighten the nuts attaching the seat to the bracket.
FIGURE 3.2 Inspecting/Tightening the Seat
Inspecting and Adjusting the Lift Column
NOTE: For this procedure, refer to FIGURE 3.3.
NOTE: The six nylon bearings installed in the outer column have been adjusted at the factory before shipping. They keep the outer column centered around the inner column and provide a smooth glide up and down. The ends of the bearings can wear with use and should be checked periodically. Approximately every six months, check the adjustment of the bearings (Detail “C”). 1. Remove the outer shroud by removing the two front and four rear mounting screws, and the self tapping screws holding the two halves of the shroud together (Detail “A”). 2. Raise the lift until about 18” of the inner column are exposed.
3. Rub a light coat of machine oil up and down the inner column until a film of oil is clinging to all four surfaces.
4. Raise and lower the lift.
5. Check the four surfaces of the inner column to see if there is a noticeable track in the oil film from the nylon bearings (Detail “B”). NOTE: If the bearings are making sufficient contact with the inner column, you will see four tracks in the oil. 6. If there is not a track in the oil film in one or more of the sides of the inner column, that sides bearings need to be adjusted IN toward the column by performing the following: A. Using a very large bladed screwdriver or a quarter held firmly with a pair of pliers, turn the bearing IN just an 1/8th of a turn (Detail “C”).
